What is parent and daughter isotopes?
The unstable isotopes change over time into more stable isotopes, in a process called radioactive decay. The original unstable isotope is called the parent isotope, and the more stable form is called the daughter isotope. Isotopes decay at an exponential rate that that can be described in terms of half-life.
What is a parent isotope quizlet?
Parent isotope. –The original unstable isotope before radioactive decay. Daughter isotope.
How do you find the parent isotope?

AfterMoreAfter one half-life half of the parent atoms are changed into equal number of daughter atoms. After the second half life half of the remaining radioactive isotope would still exist.
How does a parent isotope become a daughter isotope?
Atoms of a parent radioactive isotope randomly decay into a daughter isotope. Over time the number of parent atoms decreases and the number of daughter atoms increases. Rutherford and Soddy (1902) discovered that the rate of decay of a radioactive isotope depends on the amount of the parent isotope remaining.
What is a parent atom?
A parent atom is the atom which undergoes radio active decay in any nuclear reactions. It is also known as parent isotope. For example- U-235 decays into Th-231, U-235 is known as parent atom.
What does daughter isotope mean?
Quick Reference. An isotope produced by the radioactive decay of the nuclei of another isotope (the parent isotope). For example, lead-206 is a daughter isotope of uranium-238, which has a half-life of 4.5 billion years.
What is the difference between a parent isotope and a daughter isotope quizlet?
What is the difference between parent isotope and daughter isotope? The parent isotope is the radioactive isotope that decays and the daughter isotope is the isotope that the parent turns into.
What is an isotope quizlet geology?
Isotope. An atom with the same number of protons and a different number of neutrons from other atoms of the same element.
Why are cations smaller than parent atoms?
This is because since now the number of protons is greater than the number of electrons. Hence, there is a net posture charge, and atom is not neutral anymore. Therefore, because of this loss of electron in forming a cation, the size of the cation is smaller than its parent atom.
Why are anions larger than parent atoms?
Having more electrons than the parent atom reduces effective nuclear charge, while keeping total nuclear charge constant increases distance between nucleus and valence electrons as electron attraction to nucleus diminishes. Anions hence have bigger radii than their parent atom.
Is lead a parent isotope?
Another important atomic clock used for dating purposes is based on the radioactive decay of the isotope carbon-14, which has a half-life of 5,730 years….RADIOMETRIC TIME SCALE.
| Parent Isotope | Stable Daughter Product | Currently Accepted Half-Life Values |

| Thorium-232 | Lead-208 | 14.0 billion years |
| Rubidium-87 | Strontium-87 | 48.8 billion years |

What are isotopes distinguish between a parent and daughter isotope which one is more stable can a parent isotope decay into a daughter isotope of the same element?
Which one is more stable? Can a parent isotope decay into a daughter isotope of the same element? Isotopes are atoms of the same element that vary in number of neutrons, resulting in varying mass numbers. A parent isotope is an unstable radioactive isotope, a daughter isotope results from the decay of the parent.
How does the daughter isotope compare with its radioactive parent quizlet?
What is the difference between parent isotope and daughter isotope? The parent isotope is the radioactive isotope that decays and the daughter isotope is the isotope that the parent turns into.
What is the definition of a half life quizlet geology?
What is the scientific definition of half-life? the amount of time over which the number of parent isotopes decreases by half. Two containers hold the same radioactive isotope.
Why the size of parent atom is greater than cation?
This is because since now the number of protons is greater than the number of electrons. Hence, there is a net posture charge, and atom is not neutral anymore. Therefore, because of this loss of electron in forming a cation, the size of the cation is smaller than its parent atom.
What’s a daughter isotope?
Quick Reference. An isotope produced by the radioactive decay of the nuclei of another isotope (the parent isotope). For example, lead-206 is a daughter isotope of uranium-238, which has a half-life of 4.5 billion years.
What are the parent and daughter isotopes used to determine the age of Earth?

What is the definition of half-life in Science?
1 : the time required for half of something to undergo a process: such as. a : the time required for half of the atoms of a radioactive substance to become disintegrated.
What do we mean by the half-life of a radioactive isotope quizlet?
The half-life of a radioactive isotope is the average time it takes for the number of nuclei of the isotope in a sample to halve.
Why is the size of anion always greater than its parent neutral atom?
The reason for larger size of anion are : The negative ion is formed by gain of one or more electrons in neutral atom and the number of electron increase while the magnitude for nuclear charge remains the same . Hence size increases to accommodate the new electron.
What is the relationship between parent and daughter atoms?
The beginning isotope is called the 'parent' and the new isotope is called the 'daughter'. An isotope's half-life is the time it takes for half of the atoms of the parent isotope to change into atoms of the daughter isotope.
What is a half-life of an isotope?
Half-life is the length of time it takes for half of the radioactive atoms of a specific radionuclide to decay. A good rule of thumb is that, after seven half-lives, you will have less than one percent of the original amount of radiation.
What does half-life mean in simple terms?
Definition of half-life 1 : the time required for half of something to undergo a process: such as. a : the time required for half of the atoms of a radioactive substance to become disintegrated.
What is the half-life of a isotope?
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
How is radioactive half-life defined?
One of the most useful terms for estimating how quickly a nuclide will decay is the radioactive half-life (t1/2). The half-life is defined as the amount of time it takes for a given isotope to lose half of its radioactivity.
How is the half-life of a radioactive parent isotope defined?
The half-life of a radioactive isotope: -is the time it takes for one half of the atoms of. the original unstable parent isotope to. decay to atoms of a new, more stable, daughter isotope.
Why is it called half-life?
A half-life is the time taken for something to halve its quantity. The term is most often used in the context of radioactive decay, which occurs when unstable atomic particles lose energy. Twenty-nine elements are known to be capable of undergoing this process.
How do you find the half-life of an isotope?
2:103:12An Easy Equation to Calculate the Half-Life of an Isotope – YouTubeYouTube
Why do isotopes decay?
Every atom seeks to be as stable as possible. In the case of radioactive decay, instability occurs when there is an imbalance in the number of protons and neutrons in the atomic nucleus. Basically, there is too much energy inside the nucleus to hold all the nucleons together.
What is the difference between half-life and mean life?
Half life means 50% of original atoms decayed. Average life (Mean life) means 63% of original atoms decayed.
